You will need to wait a little more before trying to validate the license. If you’re trying to validate in order to update automatically to the latest version and you need the update now, please contact me through the profile page or support center and I will send you the update.

You need to use the dynamic tags (i.e. [sp_title], [sp_content], [sp_link] etc.) to load the content from posts into the slider, in the locations you want (i.e. layers, caption). Please see the video tutorial and the inline info from the admin area.

Are you referring to the ‘Latest news’ section, which is more narrow than it should? That seems to be due to some CSS from ‘Elementor’, which gives the column a 18.896% width, less than it needs. The CSS is in wp-content/uploads/elementor/css/post-142.css. I’m not sure why that CSS gets applied only when you add captions to the slider. Even if I delete the captions in Developer Tools, the column remains narrow. Please check if there is a settings that gives you control over the width of the column; if not, you can use CSS to override the current style.
